Studies.....

_________________________________________________________________________________

:-)...STUDIES...:-(

"Studies", most irritating word for for a child fond of playing, eating, sports, and other activities.

So, the question comes, What really "study" mean???

Most of the students settle down for studies, and don't even know what to do? how to do???
For many students study means to abandon their interesting activities for a time and open the book and start studying it...
Well, does it really mean this??
 

If we go on the technical meaning of "Study", it is:
"The devotion of time and attention to gain knowledge of an academic subject, especially by means of book."

                                   or 

a detailed investigation and analysis of a subject or situation"

Well, it's quite awkward and hard to understand and follow these terms,(especially for a student)

In this article I'm talking about average and below average students, not at all about above average students,(they are totally out of mind)

I think "studies" are the heaviest burden a child would have ever bared if he/she don't know how to handle it.

Most of the people suggest to make a perfect time table of your daily routine and follow it.

People also suggest, "early to bed and early to rise" makes your mind fresh and fit for study.

But.. my point of view is totally different from it.

ask yourself some questions:

Do you have control on your dreams?

Do you every time know what will be your future if you take this step?

Do you know what sort of mood the examiner will have while checking your papers?

I think anyone hardly knows this.

Then why put boundaries on our study time.

• there should be no time limit on studies
• there should not be any fixed time for studies,one should when he/she wants.
• the philosophy of early to bed and early to rise don't fits to today's world
• Start studying whenever your minds wishes to do it whether it's 2:30 am.

Versions of HTML

HTML-HYPERTEXT MARKUP LANGUAGE

_________________________________________________________________________________
Well we all have been using HTML of diff versions somewhere in our everyday life weather its in low powered pones or super powered smart phones and tables and many more

Through all this HTML

has gone through many changes which we will discuss today

Well so far there are currently five versions of HTML

1. HTML
2. HTML2
3. HTML3
4. HTML4
5. HTML5-most recent

Let's discuss about each of them in brief

HTML 1.0 (1989-1994)

This was the first ever version of HTML ever released.

supported inline images and text controls

Very limited styling was possible

So we can say that HTML 1.0 lacked due to its styling limitations. Every page made looked similar with same background and font.This version was only supported by Lynx and mosaic. 

HTML 2.0(1995)

This was considerably improved version

supported more browsers

supported forms with text boxes and option buttons

page background can be changed

tables were also supported

HTML 3.20(1997)

supperted creating tables and expanded options for formm elements

methamatical equations now were possible to be included in web pages

HTML 4.01(1999)

suppot for style sheet was added

scripting ability for multimedia elements was added

Now apperance and look of website can be changed just by changing the style sheet

HTML 5

HTML5 is a core technology markup language of the Internet used for structuring and presenting content for the World Wide Web. As of October 2014 this is the final and complete fifth revision of the HTML standard of the World Wide Web Consortium (W3C). The previous version, HTML 4, was standardised in 1997.

Completely changed the way webpages looked

added new elements like:

section,

article,

main,

aside,

header,

footer,

nav,

figure,

figcaption,

template,

video,audio,track,

embed,mark,

progress, meter, time,
ruby,rt,rp,
bdi, wbr, canvas
and many more

Made in India.......

Understandings.....

<marquee>Feel and understand</marquee >

Elders have said that this world is based on two things:
1.Trust
2. Understanding

But the major problem is that both of these two things are inter dependent

Trust comes when you understand that person
And you will only try to understand a person if and only if you have trust in him/her.
In today's fast running world, no one have time to invest it to understand someone.
Children don't understand their parents, parents don't understand thoughts and living mechanism of their modern society based children.
True friendships are disappearing.
Relationships are becoming biased. A perfect happy joint families are rare to find.
Relationships are dominated under the weight of workload, personal space, selfishness, and other such things.
It seems that with this modernising world and generation gap, relationships are coming to an end.
Relationships are demanding time, love, trust and understanding.
And it is our responsibility to maintain it so that we can pass it on to our upcoming generation

Here are some quotes that tells about humans:

"Trust is the glue of life. It's the most essential ingredient in effective communication. It's the foundational principle that holds all relationships."

"The trust of the innocent is the liar's most useful tool."

"The most beautiful people we have known are those who have known defeat, known suffering, known struggle, known loss, and have found their way out of the depths. These persons have an appreciation, a sensitivity, and an understanding of life that fillsthem with compassion, gentleness, and a deep loving concern. Beautiful people do not just happen."

World's first gadgets....

<marquee> world's first gadgets</marquee >

World's first Laptop...

Toshiba launched the Toshiba T1100 in 1985, and has subsequently described it as "the world's first mass-market laptop computer". It did not have a hard drive, and ran entirely from floppy disks. The CPU was a 4.77 MHz Intel 80C88, a variation of the popular Intel 8088, and the display was a monochrome, text-only 640x200 LCD. It was followed in 1987 by the T1000 and T1200. Although limited floppy-based DOS machines, with the operating system stored in ROM, the Toshiba models were small and light enough to be carried in a backpack, and could be run from lead-acid batteries. They also introduced the now-standard "resume" feature to DOS-based machines: the computer could be paused between sessions without having to be restarted each time.

World's first android phone...

The world’s first Android phone was the HTC Dream – it came to the market in October 2008 as the T-Mobile G1 in the USA and, when signing a two-year service agreement, sold for $179.Dream was the first commercially released device to use the Linux-based Android operating system, which was purchased and further developed by Google and the Open Handset Alliance to create an open competitor to other major smartphone platforms of the time, such as Symbian operating system, BlackBerry OS, and iOS.

World's first Operating system...

Well, there are many school of thoughts about who was the first to create the first operating system. 

They ranged from: 

1) DOS (actually QDOS 0.10 - Quick and Dirty Operating System) originally by Seattle Computer (later acquired by M$). 
2) CP/M, for Control Processor Monitor (was considered the first operating system for a personal computer) by Gary Kildall of the Naval Postgraduate School in Monterey, California 
3) IBM 

Many argue it was CP/M was the first. The debates continues till today. 

Worlds first Television set...

John Logie Baird FRSE  14 August 1888 – 14 June 1946) was a Scottish engineer, innovator and inventor of the world's first mechanical television; the first publicly demonstrated colour television system; and the first purely electronic colour television picture tube. Baird's early technological successes and his role in the practical introduction of broadcast television for home entertainment have earned him a prominent place in television's history.

World's first ATM...

It might just be the best idea to come to a man in the bathtub since Archimedes' time. While taking a soak, inventor John Shepherd-Barron devised what is hailed as the world's first automatic teller machine, although his claim to the title is a matter of dispute . He pitched the device to the British bank Barclay. It accepted immediately, and the first model was built and installed in London in 1967. Though the machine used PIN (personal identification number) codes, a concept Shepherd-Barron also claims to have invented, it was dependent on checks impregnated with the (slightly) radioactive isotope carbon 14 to initiate a withdrawal, as the magnetic coding for ATM cards had not yet been developed. One other difference from its ubiquitous modern counterpart: it didn't charge a fee.

World's first camera with film(paper films)...

The use of photographic film was pioneered by George Eastman, who started manufacturing paper film in 1885 before switching to celluloid in 1889. His first camera, which he called the "Kodak," was first offered for sale in 1888. It was a very simple box camera with a fixed-focus lens and single shutter speed, which along with its relatively low price appealed to the average consumer. The Kodak came pre-loaded with enough film for 100 exposures and needed to be sent back to the factory for processing and reloading when the roll was finished. By the end of the 19th century Eastman had expanded his lineup to several models including both box and folding cameras.
